    Does anyone know if there's a version of makedepend(1) for UNIX that

Don't know if this is close to makedepend(1) (it's not on any machine that I
use) but this script works fine for me.

# Make C++ dependencies.  This script depends upon the -H option built
# into cpp in System V unix.  Note: some CC shell scripts do not process
# -H properly, i.e. they do not pass it to cpp.  If this happens you will
# see an error message from patch or munch.  If this happens edit your CC
# script to pass -H to cpp.
#
# BSD users can try the -M option to cpp and then modify the script to parse
# -M output.  The Sun cpp will process the -H option and the script might
# work as is.

CC=${CC-CC}	# use CC unless ${CC} set in environment

# process all files on the command line.  Abort if no files passed

if [ "$1" = "" ]; then
	exit 1

	${CC} -E -H $file 2>&1 >/dev/null |
	grep '^\./' |
	sed "s;^\./;$file: ;"
